Airforce Delta Storm

You have to be careful not to fail in a mission, because if you do, the plane you were flying disappears and you have to find a new one using your earnings. The A-7 Corsair II is the only exception - it's the plane you start with.

As you travel across the world map, you spend fuel to move around. There are checkpoints along the way that let you rest and plan your next moves. But be aware of the enemies lurking at each checkpoint, which will attack you if you don't shoot them down first.
